An arbitrator's duty shall be independence and impartiality such as a judge who has procedurally absolute position. Independence is the freedom from others, impartiality is the status of having no-partial condition. Although these show relevance between independence and impartiality, in actuality, it is not easy to prove them. Therefore, arbitrator has to prove his or her position by opening the public of reality and by having an obligation of notification. Each country which applies Arbitration rules or Arbitration act stays the same as Korean Commercial Arbitration Board does. Hence, each country has the moral principles in order to establish a standard of judgement for essential factors and requests preferentially the impartiality and the publicity. In reality, court of justice in England excludes arbitrator who has the close relation to a person concerned. Justice in France cancelled an authorization of arbitrator because of having the economic interest to the person concerned. And also, In United States, Federal Court reverses an arbitration judgment without giving any partiality to a person concerned because of not opening a public about the relationship between arbitrator and a person concerned. Therefore, decision basis of the independence and the impartiality is standardized by the economic interest of a person concerned, professional relation, society connection, relationship between arbitrator and arbitration representative in the same case while in process of arbitration, arbitrator's nationality If arbitrator does not keep the independence and the impartiality by a position of judge, he or she has to make responsible. this duty is divided by two things: civil case and crime case. and if arbitrator does break this responsibility, he or she will get the cancellation of judge and compensation of damage. However, Korea is placed in the real circumstance without judge precedent and moral principles including the independence and impartiality. In order to getting the good reputation of international arbitration institution, this country will have to enact principles of the independence and impartiality for arbitrator.

Purpose: Intracorporeal anastomosis during laparoscopic gastrectomy is becoming increasingly prevalent. However, selection of the anastomosis method after laparoscopic distal gastrectomy is equivocal because of a lack of technical feasibility and safety. We compared intracorporeal gastroduodenostomy with gastrojejunostomy using linear staplers to evaluate the technical feasibility and safety of intracorporeal anastomoses as well as its' minimally invasiveness. Materials and Methods: Retrospective analyses of a prospectively collected database for gastric cancer revealed 47 gastric cancer patients who underwent laparoscopic distal gastrectomy with either intracorporeal gastroduodenostomy or gastrojejunostomy from March 2011 to June 2011. Perioperative outcomes such as operation time, postoperative complication, and hospital stay were compared according to the type of anastomosis. Postoperative inflammatory response was also compared between the two groups using white blood cell count and high sensitivity C-reactive protein. Results: Among the 47 patients, 26 patients received gastroduodenostomy, whereas 21 patients received gastrojejunostomy without open conversion or additional mini-laparotomy incision. There was no difference in mean operation time, blood loss, and length of postoperative hospital stays. There was no statistically significant difference in postoperative complication or mortality between two groups. However, significantly more staplers were used for gastroduodenostomy than for gastrojejunostomy (n=6) than for gastroduodenostomy and (n=5). Conclusions: Intracorporeal anastomosis during laparoscopic gastrectomy using linear stapler, either gastroduodenostomy or gastrojejunostomy, shows comparable and acceptable early postoperative outcomes and are safe and feasible. Therefore, surgeons may choose either anastomosis method as long as oncological safety is guaranteed.

This study focused on finding the variation of medical service utilization, paths of medical service utilization and medical payments of the patients died by cerebrovascular diseases. For this study, data of the one-year episodes of the health insurance subscribers died in 2004 were selected. The frequency of medical visits, the lengths of stays, the days of outpatient visits, the total period of medical services and the total medical payments were compared by the characteristics of the suppliers and utilizers. This study is useful in reviewing the equity of medical service utilization because it analyzed variance in utilization by episodes. In oder to collect accurate data of the patients died by cerebrovascular diseases in 2004 the 2004 reimbursement data of all medical institutions were matched to the data of funeral fee payment by the National Health Insurance Corporation from January 2004 to May 2005. The major results of the study are as follows. The variation of medical service utilization of cerebrovascular diseases was influenced by supplier factors suppliers, such as types and locations of medical institutions and user factors such as sex and age. It was suspected that the reimbursement by fee-for-service contributed to the variation quite a lot, but we could not compare the variation between the different reimbursement systems in Korea. On the basis of analyzing results this study suggests that the factors of suppliers and utilizers should be reviewed to reduce the under use and over use expressed by variations of medical service. The processes of care, effective communication and management system should be investigated for the equity of medical service utilization and also. alternative medical services would be recommended to reduce the high medical payment. Additionally to find other causes of variation further in depth study controling the severity of diseases, socio-economic status of the users and the system factors is required.

A railway station appears in the form of multi-use station building where cultural and commercial elements such as shopping and leisure are mixed, getting out of simple space configuration oriented to the space for station work, where a passenger stays for a little while. Now, a railway station is a place expanded to the inside of city, and builds a relationship with urban fabric, and therefore it should receive the social change in the time together with the surrounding infrastructure, and should inevitably form the urban environment. And it should become the 'Place' so as to be capable of playing a role of buffer and a role of regional gateway landmark by making users included in the inside through various uses with regard to the dispersed urban connection. Hence, this study is intended to examine the planning through the place branding of railway station. In the method of research, the characteristics that place branding had was investigated, and an analysis was made on the basis of 10 place branding strategic elements and 6 railway design guidelines. And it was intended to set a direction in which the existing place branding strategy could be applied to the railway station, and was intended to derive the place branding planning strategic elements of railway station. Hence, the planning can be classified into the following 5 kinds in connection with railway station. First, identity should be embodied through the strategy of constructing the symbolic image of railway station. Second, a role of mediating variously approaching flows in the city should be played. Third, the spatial layout of railway station, which can increase the efficiency of use, should be arranged. Fourth, special characteristics should be intensified through creative storytelling that stimulates emotion. Fifth, an organic change is gradually necessary for sustainability. These planning elements should be applied in harmonious combination. Therefore, a new railway station can be maded by building identity and placeness and by giving the value through these planning directions in the future.

The study is intended to produce a modern Cheollik style one-piece dress that stays within the traditional concept of beauty. Specially, the study focuses on Cheollik of the Joseon Dynasty among various traditional costumes as its motif. As the Joseon Dynasty changed, the forms of Cheollik changed with it. People of all classes from the commoners to king wore it. Cheolik was different from other traditional costumes because the top and bottom were connected and so it was an easy to wear one-piece clothing. Initially, the ratio of upper and lower parts was one to one, but later on, the ratio changed to 1:2 as the topcoat became wider and length of the skirt was lengthened. Diverse types of pleat emerged such as fine pleat, opposite pleat and long pleat. Collar and string were also diversified and studied by applying the components. To study it, the author considered the previous studies about Cheollik first. Then, the Cheollik of the Joseon Dynasty was reproduced. Thirdly, with the motif of Cheollik components, the materials suitable to a one-piece dress design were selected, dyed naturally. Finally, One piece dress design was utilized by using the components and features of Cheollik. 8 pieces of one-piece dresses were made as an ordinary dress and the materials such as ramie, Oksa, hemp, silk, Yeon-hwamun dan and artificial silk were used. Hopefully, other traditional costumes can develop as a practical and ordinary dress.

Purpose: The purpose of this study was to examine the effect of a blood glucose control protocol for medical intensive care unit (ICU) patients. Methods: The subjects were recruited from medical ICU adult patients whose blood glucose levels exceeded 200 mg/dL in two consecutive tests. The experimental group (n=62) received the modified Yale (MY) insulin protocol, whereas the control group (n=64) was treated with the conventional insulin therapy methods. Results: In the experimental group, the mean blood glucose levels (p<.001) and the time to reach the target range of glucose (p<.001) decreased significantly while the incidence rates of a target range of glucose of 100-140 mg/dL (p<.001) increased significantly as compared to the control group. However, no statistically significant differences were found in the incidence of hypoglycemia(p=.644), or the number of glucose tests (p=.236) between the groups. The length of stays in the ICU (p=.001), ventilator care days (p=.038), and the Sequential Organ Failure Assessment (SOFA) score (p=.029) in the experimental group were significantly lower than those of the control group. Conclusion: Application of the protocol was effective in improving the state of blood glucose control in medical ICU patients. Therefore, this protocol is expected to be used as a part of nursing intervention in critical care nursing.

Consumer education which changes human value and attitude to attain practice is necessary to solve the problem of environmental, social, and economical sustainability resulted from material and present-oriented consumption and decrease the effect of consumption on the sustainabilities. However, since the present consumer education is biased toward a traditional viewpoint of economical consumption, management of allowances, and rational purchase and its teaching method still stays on memorizing, cramming and one sided lecture, consumer education containing a key value of sustainable development have not been carried out successfully, Specifically, the consumer education in an elementary school treats mainly just on environmental conservation and economical knowledge even though quite much time is arranged in every school year. So, complement of contents such as understanding of relation between natural resources and consumption and the role and responsibility of a consumer is required to emphasis the sustainable development. In this work, a student-oriented educational drama programme for consumer education is developed with respect to an familiar theme of resources such as water, wood, food, and electricity. Educational drama is an efficient teaching method for consumer education of an elementary school student since it makes students experience virtual situation and produce an interest and active participation. How to execute consumer education in an elementary school textbook was analyzed and an educational drama programme was developed and applied, and finally, the programme was qualitatively improved. The paper survey on five teachers practicing the present programme reveals that is it can be affirmatively evaluated since it is familiar to students and leads to their interests and participation. Consequently, it can be confirmed that the present programme can be effective to perform consumer education for sustainable development.

Arteria radialis is a branch of the brachial artery extending down the forearm around the wrist where it closes to skin surface. In the oriental medicine, the skin above arteria radialis has an important role because oriental medicine practitioners put their finger tips on the area, and diagnose patient's health conditions by feeling the pulsation of the arterial contraction. The finger tip diagnostic method relies on subjective decision of the practitioner; and there is a need to develop an objective diagnostic modality. The pulsation of the arterial contraction appears not only a movement on the site but also as temperature fluctuation due to pulsatile feeding of warmer blood. The goal of this study is to demonstrate a feasibility of using an infrared camera quantitatively to detect the temperature fluctuation on the skin. Clinical important three different areas, called chon, gwan, chuk, near a wrist where the arteria radialis reaches close to skin surface are marked with small pieces of surgical tape. A high-speed and high-resolution infrared camera with a 3 cm of field of view measures these areas for 10 second at 200 frames per second with a 320*240 pixel size. The pulsatile temperature fluctuation is calculated after passing a band pass filter to remove any stationary temperature over 10 second. The temperature fluctuation of a healthy male volunteer is measured at a room temperature as a control, and is compared with another measurement performed after 20 minutes staying in a room at a 40 degree Celsius. This comparison is repeated for three times, and indicates that the fluctuation increases after staying 20 minutes in the warm room. This increase becomes smaller when the person stays in the warm room with an acupuncture treatment that decreases body temperature. So that an objective diagnostics on the site may become feasible.
